Introduction
The MLSUCB is an embedded controller/web-page server for remote monitoring and control of
Ex-Or Digital Managed Lighting Systems, (MLS Systems). It also has the capability of presenting
its status information and receiving commands in BACnet protocol form. The MLSUCB has two
major components - the MLSJC6 and MLSJC6PSU which may also be ordered separately.

MLSUCB Mounting and Wiring Instructions for MLS System
Applications
Enclosure mounting
The MLSUCB Enclosure houses the MLSJC6 and MLSJC6PSU mounted on a DIN rail.
Affixing the enclosure to the wall
The MLSUCB enclosure can be wall mounted by fixing the wall mounting lugs to the corner holes
on the rear side as shown in the fig.1 below. The wall mounting lugs and the fixing instructions are
supplied with the enclosure.

holes on the MLSUCB Enclosure
Wiring mains to the MLSJC6PSU
The entry for the mains wiring can be made by drilling a conduit of around 20mm at the bottom or
either side of the enclosure. These wires are to be terminated at the MCB and Mains terminal
blocks on the right side of the MLSJC6PSU. The MCB and the terminal blocks are prewired to the
MLSJC6PSU in the factory as shown in Fig. 2 below.

DIN Rail mounting
The MLSJC6 and MLSJC6PSU can be individually ordered for mounting on a DIN rail.
Mounting the MLSJC6 and MLSJC6PSU on the DIN rail
The MLSJC6 unit base has a moulded DIN rail slot and a locking clip. A 35mm wide DIN rail is
required for mounting the MLSJC6 and MLSJC6PSU. The following steps provide DIN rail
mounting instructions for the MLSJC6 and MLSJC6PSU.
1. Lever out the locking clip of the MLSJC6 using a screw driver. Place the pre-commissioned
MLSJC6 unit onto the DIN rail and then release the securing clip .Push back if necessary .Turn
the unit over to check that the rail is secured in the unit

2. Place the 5 DIN rail terminal blocks onto the left hand side of the MLSJC6 with the side end
plate fitted against the MLSJC6 unit .Push down on the Terminals to clip onto the rail
3. Place the power supply onto the DIN rail on the right hand side of MLSJC6. Lever out the fixing
tab and push down on the power supply. Push the fixing tab back in to se

5. Place the Neutral (Blue) terminal onto the DIN rail as shown. Push down on the right hand side
of the terminal to clip onto the DIN rail
6. Place the Earth (green & yellow) terminal onto the DIN rail as shown next to the Neutral
terminal. Tighten down the Earth (green & yellow) terminal using a screwdriver to secure to the
DIN rail
7. To keep the final assembly together, secure at both ends with DIN rail end stop. This also
prevents the assembly from sliding on the DIN rail.

Power supply Connections
The MLSJC6 is powered by MLSJC6PSU which is a DIN rail Power supply unit. The MLSJC6PSU
converts mains AC voltage to 15VDC for powering the MLSUCB. The screw type terminals for the
Mains connections are on the bottom side and the 15VDC connections on the top side. The cable
for the power supply connection from MLSJC6PSU to MLSJC6 is supplied along with the
MLSJC6PSU module.

Documenting the wiring plan
The next stage after installing the unit is commissioning. This requires knowledge of the wiring
plan.
It is therefore important to provide this information preferably using the architectural plans provided
prior to installation. This should include the following when handing over and getting sign off with
the client, but it must be noted that these assume ideal circumstances and that an architect has
available such plans.
RB2000 locations
Zones and their respective RB2000 address must be clearly marked.
The Ballast type and timeout period should also be listed.
Zone identities. Such as room names or numbers
LCM locations
Emergency Ballasts
Some of this information may only be available from those who commission the MLS lighting
control system which may or may not be an Ex-Or commissioning Engineer.

MLSUCB Product Description
The MLSUCB is an embedded controller/web-page server for remote monitoring and control of
Ex-Or Digital Managed Lighting Systems, (MLS Systems). It also has the capability of presenting
its status information and receiving commands in BACnet protocol form. The MLSUCB has two
major components - the MLSJC6 and MLSJC6PSU
When utilised for lighting control and lighting status display application (i.e. no emergency testing)
the MLSUCB takes the role of bus master on the RS485 spine linking a number of RB2000s each
of which drives an MLS bus capable of supporting up to 100 separate lighting zones comprised of
up to 200 individual presence detectors with photocells.
Control functions in the lighting application can be either pre-programmed actions governed by an
onboard time-of-day clock or manual interventions delivered via the supported web-page from any
co-networked Personal Computer running a web-browser. With the BACnet capability installed
real-time control actions can also be initiated by remote BMS devices.
Conversely via the BACnet protocols information gathered by the lighting system’s detectors,
typically occupancy data can be passed to other BMS disciplines.
The MLSUCB supports the automated testing of DALI based emergency luminaries and signs. By
connecting a single emergency luminaire to individual channels of the LCM, the user can create
automated test schedule for those luminaires. Each individual channel of the LCM can have one
emergency ballast connected. This output is individually addressed; hence any failures in the
emergency luminaires can be reported back to the MLS front end application. When using the
emergency testing element of the system the number of available MLS zones for BACnet
transmission is reduced.
BS 5266 (BS EN 50172) requires that emergency luminaires and signs are tested in accordance
with a specified schedule in order to ensure correct operation. The MLS Emergency Lighting Test
system removes the uncertainty of manual testing and ensures compliance with IEC62034. It is
designed to provide comprehensive monitoring and reporting for DALI Emergency Luminaires and
Signs in accordance with BS EN 62386-202.
